The control centre for the various corporate activities is our head office in Rotkreuz (Switzerland), where there is a tailor made infrastructure consisting of production of PTFE/PFA butterfly valves, workshop, store, administration office and training room. Rotkreuz is, on the one hand, head office of the group but, on the other, it is also a typical sales and marketing organisation with subsidiaries in Italy, Austria, Hungary, Spain and France. Furthermore we run a production factory for elastomer seated butterfly valves in Madrid, Spain. In other markets we work together with qualified sales partners. Innovative thinking and market orientated actions will continue to make InterApp stand out in the future.
